VIM-2x Ethernet Module Port Option Card
The VIM-2x Ethernet Module option card, shown in Figure 108, allows you to add up to two 10-gigabit
SFP+ optical ports to the VIM slot on the rear panel of the X460-G2 series switch. These ports support 1
GbE and 10 GbE SFP and SFP+ transceivers.

TM-CLK Clock Module
The TM-CLK Clock Module provides an Oven-controlled Crystal Oscillator (OCXO) for use as a reference
frequency for SyncE and 1588v2 precision time features. The OCXO is precise to +-2 nanoseconds (ns)
with time accuracy +50 to -65 ns. The ExtremeXOS configuration selects the input to the clock module
from a SyncE master port or a 1588v2 grandmaster clock. The TM-CLK module is required for SyncE on
